Arithmetic operations are basic calculations used daily in mathematics. These operations include addition, subtraction, multiplication, and division. The order in which we perform these operations is crucial and often guided by the mnemonic PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

When solving arithmetic problems, always start with operations inside parentheses. If there are no parentheses, continue by addressing exponents. Then, handle multiplication and division from left to right, followed by addition and subtraction from left to right.

In our specific exercise, the arithmetic operations involved are subtractions only, but the sequence of operations remains important.

Subtraction is a fundamental arithmetic operation representing the removal of objects from a collection. It can also be seen as determining the difference between two numbers.

To understand subtraction, it's essential to grasp a few key points:

• If you subtract a larger number from a smaller number, the result will be negative.
• Subtraction is not commutative, meaning the order in which you subtract numbers matters.
• Rewriting subtraction as adding the negative value can sometimes simplify the process.

In the example provided, the operation starts with subtracting 8 from 5, resulting in -3. Next, we subtract 3 from -3. Visualizing or using a number line can be helpful here.

Begin at -3 on the number line and move 3 units to the left, landing on -6. Therefore, the final answer is -6.

Negative numbers are numbers less than zero and are often represented with a minus sign (-). They are critical in various real-life scenarios, such as temperatures below freezing, financial debts, and more.

When working with negative numbers, a few rules are helpful:

• Adding a negative number is the same as subtracting its positive counterpart. For example, 5 + (-3) is the same as 5 - 3.
• Subtracting a negative number is the same as adding its positive counterpart. For instance, 5 - (-3) is the same as 5 + 3.
• Negative times negative results in a positive number.

In our exercise, the number -3 is subtracted by another 3, resulting in a deeper negative number, -6.

Negative numbers can sometimes confuse, but regularly practicing with examples helps to build confidence and accuracy in using them.
